- Radiology of the pharyngoesophageal segment in patients with dysphagia relies on evaluation of both morphology and function. Video- or cineradiographic techniques are necessary. Retention of contrast material above the cricopharyngeal muscle can be due to small pseudodiverticula or true diverticula. Both phenomena are due to dysfunction in the pharyngoesophageal segment. To develop into a true diverticulum it is probably necessary to have a congenital defect between the muscle layers in the pharyngoesophageal segment.

- In general, primary surgery of thyroid carcinoma should consist of total thyroidectomy and lymph node dissection of the cervicocentral compartment. Exceptions are cases of papillary microcarcinoma and prophylactic surgery due to multiple type 2A endocrine neoplasia. Lymph node dissection beyond the cervicocentral compartment also should be compartment-oriented. It is generally indicated if lymph node metastases have been proven. Concerning clinically proven medullary thyroid carcinoma, bilateral cervicolateral lymph node dissection is generally indicated, since lymph node metastases may be missed preoperatively but are often found histologically. In patients with parathyroid carcinoma, en bloc ipsilateral cervicocentral lymph node dissection should be performed in addition to parathyroidectomy and hemithyroidectomy. Lymph node dissection should always be performed systematically, since lymph node metastases may be missed both clinically and by imaging techniques.

- In contrast to primary hyperparathyroidism, parathyroid carcinoma is a rare disease. In patients with hyperparathyroidism jaw tumor (HPT-JT) syndrome, caused by germline mutations in HRPT2, the development of parathyroid carcinoma is estimated to be 10-15%. This review summarizes the clinical and molecular genetic data of about 100 patients in the literature and three of our own cases. Unfortunately, osteofibromas, which might enable timely diagnosis of HPT-JT syndrome, occur in only about 30% of patients; about 80% have uniglandular disease. Based on the current data, a general recommendation to perform prophylactic parathyroidectomy cannot be given. However, thorough screening of patients at risk is mandatory. Of note in patients thought to have sporadic parathyroid carcinoma, germline HRPT2 mutations are found in up to 20%. Hence, any patient with parathyroid carcinoma should undergo HRPT2 mutation analysis.

Parastomal hernia treatment with prosthetic mesh repair

- After stoma formation, parastomal hernia develops in 30-50% of patients, with one-third of these require operative correction. Recurrence rates are very high after suture repair of parastomal hernias or relocation of the stoma. Open or laparoscopic mesh repairs have resulted in much lower recurrence rates. Long-term follow-up of the various techniques for parastomal hernia repair is lacking, as are randomized trials. A prophylactic prosthetic mesh placed in a sublay position at the index operation has reduced the rate of parastomal hernia in randomized trials. A prophylactic mesh in an onlay position, a sublay position, and an intraperitoneal onlay position has also been associated with low herniation rates in non-randomized studies. Although several questions within this field still have to be answered, it seems obvious that use of a mesh represents a suitable measure for the prevention of parastomal hernia as well as parastomal hernia repair.

- Background: Since 2015 operations performed in the field of endocrine surgery have been entered into the European registry EUROCRINE®. The aim of this analysis was a description of the current healthcare situation for adrenal surgery in a homogeneous healthcare environment corresponding to the German-speaking countries—or to the presence of the working group on surgical endocrinology (CAEK) of the German society for general and visceral surgery (DGAV)—and to assess the adherence to current international treatment guidelines. Methods: An analysis of the preoperative diagnostics, the applied operative techniques and the underlying histological entities was carried out for all operations on adrenal glands in Germany, Switzerland and Austria, which were registered in EUROCRINE® from 2015 to 2019. Results: In the total of 21 participating hospitals from the German-speaking EUROCRINE® countries, 658 operations on adrenal glands were performed. In 90% of cases unilateral adrenalectomy was performed, in 3% bilateral adrenalectomy and in 7% other resection procedures. In 41% the main histological diagnosis was an adrenocortical adenoma. In 15% malignant entities were detected on final histology, including 6% adrenocortical carcinoma (ACC) and 8% metastases to the adrenal glands. 23% of the operations were performed for pheochromocytoma. This entity was primarily resected using minimally invasive approaches (82%), whereas minimally invasive techniques were applied in 28% for ACC and in 66% for metastases to the adrenal glands. Conclusion: Surprisingly, following adrenocortical adenoma and pheochromocytoma, the third most common histological entity was metastasis of different extra-adrenal primary tumors to the adrenal gland. Of the operations for ACC 28% were scheduled for minimally invasive techniques, but conversion to open surgery was necessary in 20%. The analysis revealed discrepancies between treatment reality and international guideline recommendations that raise questions, which will be addressed by an updated version of the EUROCRINE® module for the documentation of adrenal surgery.

- Dry eye disease is a common ocular surface disease that significantly affects the quality of life. Little is known about a potential impact of the disease on corneal morphology. This study was carried out to investigate for the first time if dry eye disease induces changes in corneal density and thickness. In total 97 patients suffering from dry eye disease and 33 healthy age-matched individuals were included in this prospective, randomized study. Corneal morphology was documented with Scheimpflug photography and analyzed for central corneal thickness and corneal density in five anatomical layers (i.e. epithelium, Bowman membrane, corneal stroma, Descemet membrane and endothelium). Corneal density was significantly reduced in the epithelium (p = 0.0053), Bowman membrane (p = 0.0049) and Descemet's membrane (p = 0.0385) in patients with dry eye syndrome compared to healthy controls. This decrease was age-dependant. Furthermore, central corneal thickness was significantly reduced in patients with dry eye syndrome compared to the control group (p = 0.0495). The change was again dependent on age with lower values at higher age. Central corneal thickness increased with age in the control group. The results of this study indicate that corneal morphology is subject to significant alterations in patients with dry eye disease. Scheimpflug photography provides not only unique information in lens trials but is also able to detect changes of corneal anatomy. However, further investigations with other anterior segment imaging techniques, such spectral domain optical coherence tomography (SD OCT/PentacamA (R)) are necessary to further evaluate the clinical consequences of these findings.
